Fitted some basin new taps & a new pop up waste today. Apart from checking
for plumbing & waste leaks I always check that the overflow is working as
well.

Combi boiler, so hot & cold at the same pressure, which was pretty high.

It surprised me how quickly the sink filled up. The overflow simply would
not have coped with the flow of water from even one tap on full blast, let
alone both. So it would be largely ineffective as an overflow - wouldn't
prevent a flood if a tap was accidentally left on.

I wonder if sink & basin designers have thought about the flow rates now
that hot water could be at mains pressure?

Yes - that's why they're smaller. ;-)

My Doulton pedestal wash basin (correctly installed) is within 3mm of
overflowing the front before any water flows down the small overflow, it's
so ineffective it may as well not be there!

Basins are sold that have no overflows at all.
I recently fitted one in the downstairs WC.
The waste is fitted with an anti-siphon trap which is slow to discharge, the
running water can easily overtake the discharge rate.
The kids are now both teenage fortunately (?) and so far no-one's left the
taps running .

Someone will come along shortly to tell you it is flow not pressure that
matters and that a combi will not fill a bath as quickly as a conventional
system.

Looking closer I can see Mr Plowman already has.

Predictable me.

Normally dribble would be along to say the solution is two combis but I'd
guess he's finally been sectioned.
